実験手順
A mixture of p-hydroxyphenylacetamide (3.8 g), ethyl 4-bromobutyrate (3.6 ml) and K2CO3 (3.45 g) was stirred for 12 hr in DMF (30 ml). The mixture was diluted with water (100 ml); the solid was filtered and air dried. Crystallization of the solid from ethanol gave 4 g (60%) of the title compound as white crystals; mp 144.5°-145.5°.
